nxdumptool/source/core/hfs.c
Pablo Curiel 50deeeb41b Improve directory layout while we still can.
The directory layout is partially based on the C++ namespaces we're currently using.

Other changes include:

* devoptab: move directory into "core".

* fatfs: move directory into "core".

* GameCardTab: move portions of logic from PopulateList() into their own methods.
* GameCardTab: use a macro to generate the properties table.
* GameCardTab: use a macro to add ListItem elements.
* GameCardTab: update AddApplicationMetadataItems() method to also display the number of DLCs available in the inserted gamecard for each application whenever possible.

* Makefile: remove all extra entries from the INCLUDES variable.

* nxdt_includes: move HOS version structs into their own header file.

* tasks: move code for each individual task into its own file(s).

* title: update titleGetGameCardApplicationMetadataEntries() to also count the number of DLCs available in the inserted gamecard for any given base application.
* title: reorder gamecard application metadata entries by name before returning the buffer in titleGetGameCardApplicationMetadataEntries().
